# Check that a module argument is passed, also when a default is available
# (but not needed)
#
# When the default is needed, we currently fail to do what the users expect, as
# we pass our own argument anyway, even if it *turns out* not to exist.
#
# The reason for this is that we don't know at invocation time what is in the
# _module.args option. That value is only available *after* all modules have been
# invoked.
#
# Hypothetically, Nix could help support this by giving access to the default
# values, through a new built-in function.
# However the default values are allowed to depend on other arguments, so those
# would have to be passed in somehow, making this not just a getter but
# something more complicated.
#
# At that point we have to wonder whether the extra complexity is worth the cost.
# Another - subjective - reason not to support it is that default values
# contradict the notion that an option has a single value, where _module.args
# is the option.
